[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 to 5, reference numerals 1 and 2 denote fingertip protection plates of the present example attached to the outer surfaces of the thumb portion 5 a and the four finger portions 5 b of the basement 5.

As shown in FIG. 2, the protective plates 1 and 2 have a thickness of several millimeters, and preferably a thickness of about 1.5 to 2 mm. Use a hard material such as metal or synthetic resin such as stainless steel or iron plate having a height that does not disturb during use, preferably a height of about 10 to 20 mm. It is formed in a band shape so as to match equally. At the lower end portions of the outer surfaces 1a, 2a of the two plates 1, 2 at the end portion on the finger crotch portion 2c side between the thumb and the four fingers when attached to the basement 5, preferably 4 to 5 mm The width is 2-3mm
The flat support pieces 3 and 4 which protrude horizontally with the length of are provided.

The protective plates 1 and 2 thus formed can be attached to the underground 5 by appropriate means.
As an example, the base 7 to which the upper 6 is adhered is formed by flow-forming, or the base 6 is formed by a normal processing step of sewing the upper 6 and the base 7 together, and then the two fingertips of the base 5 are formed. Elastic material pieces 8 and 8 made of rubber or synthetic resin having appropriate elasticity are firmly fixed to the outer peripheral side face portion with an adhesive, and the outer peripheral surface of these elastic material pieces and the upper surface 6 Protective plates 1 and 2 are installed on the overhanging edge 7a of the bottom 7 which slightly protrudes outward from the base, and both plates are firmly integrated with the overhanging edge 7a via an adhesive as well. In some cases, the two plates are glued together and fixed each time underground. The protection plates 1 and 2 need to be fixed so as to be substantially perpendicular to the bottom 7 each time underground.

[0010] As described above, the protection plates 1 and 2 attached to the fingertips of the underground base 5 are fixed to the peripheral surfaces of the elastic pieces 8 and 8, so that both plates are on the outer peripheral side surfaces of the fingertips 5a and 5b. Stably fixed along the part, even if a heavy object falls on your fingertips during wear, the falling object is reliably received at the upper ends of the protective plates 1 and 2 and the impact of the fall is buffered. Therefore, there is no danger of the falling object directly hitting the fingertip and causing injury, and the work can be performed safely and promptly.

Further, since the protection plates 1 and 2 of this embodiment are provided with support pieces 3 and 4 at the lower ends of the outer surfaces 1a and 2a, respectively.
As shown in FIG. 5, the two plates are supported by the support pieces 3 and 4, so that the fixing stability and the strength against falling and bending are increased,
Is received at the upper ends 3b and 4b, and even if a large load is applied from above, the outermost member falls outward and is hardly bent. In particular, by providing the support pieces 3 and 4 at the ends on the finger crotch 5c side, the protection plates 1 and 2 can be made hard to fall and bend toward the other finger, that is, the center of the foot. Even if a heavy object falls on either side of the part 5a or the four-finger part 5b, there is no possibility that both plates bend toward the center of the foot and hit the dropped object directly to the fingertip.

Further, even if the toe collides with the mounted object during walking, the toe is protected by the outer surfaces of the protective plates 1 and 2, and the impact is absorbed by the elastic pieces 8 and 8 so that there is no risk of damaging the fingertip.
Furthermore, since the protective plates 1 and 2 are provided outside the toe, the degree of freedom and exercise performance of each finger are not different from those of a normal underground, so that a good feeling of wearing and stability can be obtained. The elasticity of the elastic pieces 8, 8 provides a cushioning function between the two plates and the fingertips to ease the comfort, and also saves materials and weight compared to the conventional structure in which the entire fingertips are covered. Therefore, there is an advantage that processing is easy.

As described above, the supporting pieces 3 and 4 are
By protruding the protection plate, the bending resistance of the protection plate is increased. However, if the support pieces 3 and 4 are protruded flat at an appropriate width at the lower end of the protection plate, as shown in FIG. It may be provided at a plurality of portions such as both ends of the outer surfaces 1a and 2a of the protection plates 1 and 2 (FIG. 2A), or may be provided over the entire lower end portion of the outer surfaces 1a and 2a (FIG. (B)).

FIGS. 7 and 8 show a second embodiment of the present invention. In this embodiment, a fingertip protection plate 10 is made of metal, synthetic resin, or the like having an appropriate height and thickness so that it can be fixed to work shoes 12. As shown in FIG. 6 (B), the support member 11 is curved into a band shape substantially equal to the outer surface of the entire toe portion, and flat support pieces 11 are provided around the entire outer surface of the lower end portion. It is formed by projecting about 3 mm.

The protection plate 10 of the present embodiment is mounted, for example, on the narrow groove 1 in which the protection plate fits into the overhanging edge 13a of the sole 13 that has not been streamed.
A projection 13c projecting upward along a contact portion between the upper 3b and the upper 14 is formed.
4 is suspended and adhered, an adhesive is applied in the narrow groove 13a, and the protection plate 10 is fitted into the groove. Further, on the upper surface of the support piece 11 of the protection plate 10, unflowed rubber or The flowable rubber sheet is passed through the non-flowable rubber paste, and the unflowed elastic material pieces 15
The protective plate 10 can be fixed by forming the shoe sole 13 by the flow molding on the sole.

As described above, even with the protection plate 10 attached to the fingertip of the work shoes 12, the heavy object dropped on the fingertip can be reliably received at the upper end of the protection plate 10, so that the fallen object hits the fingertip directly and the injury occurs. There is no danger of work, and the work can proceed safely and quickly. In addition, the protective plate 10
The support piece 11 provided on the outer surface of the protective plate 10 prevents the protective plate 10 from falling down and bending, and high falling bending resistance is obtained. Also, when manufacturing the work shoes 12, the upper 14
Since the protective plate 10 can be attached after bonding the protective plate 10 to the shoe sole 13, there is no need to perform any special processing on the upper 13, and the protective plate 10 can be easily formed only by bending the protective plate 10. The production cost can be kept low.

[0017]

As described above, according to the fingertip protection plate of the present invention, the hard plate material is formed in a band shape along the outer surface of the toe, and is formed by projecting a flat support piece at the lower end of the outer surface. Since it is possible to produce at low cost without any trouble in processing, and if this is attached to the fingertip of footwear,
Even if a heavy object falls during use, the falling object can be reliably received at the upper end of the protective plate, and the protective plate can prevent the protective plate from being deformed. The fingertip can be prevented from being damaged, and the fingertip can be safely protected. Since the fingertip protection plate of the present invention is installed outside the toe, the degree of freedom and exercise performance of the toes are not different from ordinary work shoes, and a good wearing feeling and a stable feeling are obtained. Can be.
